I'm running Mist on Windows, and I want to change the datadir because I'm running out of space on the C drive, but I want it to be on the actual Ethereum blockchain.

Will I run into trouble if I change the datadir?

  • No, you can simply change the datadir to whatever you like. Do you know how this is done in mist?

    To change it in Mist, first run geth with the --datadir flag, and then launch Mist. (They both need to be running) Feb 4 '16 at 10:53

No, you are free to change the data directory. It's just a place to store the blockchain, it doesn't mean that you would be on a different chain.

    but does mist allow the --datadir flag?

Changing the datadir, by using --datadir is all OK.

Running Geth on the testnet is a different flag, --testnet.

If you've been using Geth and have ether in your accounts, don't forget to backup all your keystore files before deleting the old datadir.
